[Bug 557429] Re: booting out of sync RAID1 array fails with ext3 (comes up as already in sync)

[Phillip Susi]

I have reproduced this on Karmic by manually assembling, stopping, and
reassembling the array based on two lvm volumes.  When mdadm
--incremental is run on the first degraded leg of the mirror, it
activates it since it now has one out of one disk with the second disk
flagged as faulty, removed.  You would think that the second disk would
show the first as faulty,removed as well, but it only shows it as
removed.  When mdadm --incremental is run on the second disk, it happily
starts using it without a resync.  I believe this should fail and refuse
to use the second disk until you manually re-add it to the array,
causing a full resync.  I have mailed the linux-raid mailing list about
this.


** Changed in: linux (Ubuntu Lucid)
